Back in October I asked a question about multipathing in z/Debian. I've since resolved my problem with getting the multipathing device definitions to hold across an IPL, but now I'm having trouble booting with root mounted on a multipathed, LVM'd volume on z/Debian. It appears to be within the order of things. Of course, multipathing should come first, then LVM, then the mounting of root, but what I always get is the message "mounting root on /dev/mapper/system-ROOT" (in other words, I've coded /etc/zipl.conf correctly), then unable to find volume group "system", then it drops into initramfs. I try to issue a "vgchange -ay system", but it can't find the volume group "system", nor can it find the multipath'd volume (/dev/mapper/mpath0 or mpath1) to use as its PV's.
ALERT! /dev/mapper/system-ROOT does not exist. Dropping into shell! cat /proc/cmdline root=/dev/mapper/system-ROOT ro rootdelay=10 BOOT_IMAGE=0 cat /proc/modules dasd_eckd_mod zfcp scsi_transport_fc scsi_mod dasd_fba_mod dasd_mod dm_multipath dm_snapshot dm_mirror dm_mod How do I get my multipath definitions and LVM configuration to run before root is mounted?
